CHURN-DASHER.

SPECIFICATION forming part of Letters'Patent No. 646,170, dated March27, 1900.

Application filed August 29, 1899. $eria1No.728,898. (No model.)

To all whom it may concern:

Be it known that I, ASA HAZELTON, a citizen of the United States,residing at Middletown, in the county of Montgomery and State ofMissouri, have invented a new and useful Churn-Dasher, of which thefollowing is a' essary to remove the receptacle for containing thetempering liquid, so that the latter may be placed in the receptacle;and the essential object of the present invention is to obviate theconstant removal of the receptacle and at the same time to permit of theready introduction of the tempering liquid into the receptacle while thedasher is in motion.

A further object is to provide an improved arrangement of thedasher-blades in respect to the tempering-receptacle, so that an easyand effective operation of the dasher is had.

To these ends the present invention 0011- sists in the combination andarrangement of parts, as will be hereinafter more fully described, shownin the accompanying drawings, and particularly pointed out intheappended claim, it being understood that changes in the form,proportion, size, and the minor details of construction may be madewithin the scope of the appended claim without departing from the spiritor sacrificing any of the advantages of the present invention.

In the drawings, Figure '1 is a perspective view of a churn-dasherconstructed in accordance with the present invention. Fig. 2 is alongitudinal sectional view thereof. Fig. 3

p is a horizontal transverse sectional view of the improved dasher.

Corresponding parts in the several figures of the drawings aredesignated by like characters of reference.

Referring to the accompanying drawings, it will be seen that the presentdasher comprises upper and lower heads 1 and 2, respectively, which aresubstantially triangular in shape and preferably equal in size.

Radial arms 3 project outwardly from each corner of the triangular head,and the respective upper and lower arms are connected by verticaldasher-blades 4, which are disposed in the vertical planes ofthe'adjacent arms 3. Intermediate of the dasher-blades is located thebody or receptacle 5, which is designed to contain .the temperingliquid. The cross-sectional shape of this receptacle is triangular, asbest shown in Fig. 3 of the drawings, and is of substantially the samesize as the triangular body portions of the upper and lower heads 1 and2. The upper and lower ends of the receptacle are closed by therespective heads 1 and 2, and the angular corners thereof are arrangedadjacent to the respective dasher-blades 4 and the latter are spaced asuitable distance from the adjacent corners of the receptacle, asclearly shown in Fig. 3.

Provided in the upper head 1 and centrally of the receptacle 5 is anopening 6, through which the tempering liquid is adapted to beintroduced into the interior of the receptacle. Surrounding this openingand projecting upwardly from the upper head 1 is a threaded flange 7, towhich the dasher-stem 8 is removably connected. The lower end of thedasher-stem is provided with a threaded coupling member, which isadapted to be fitted to the threaded flange 7 or other coupling member,so that the dasher-stem may be detachably connected to the dasher.

During the churning operation it is essential that the cream bemaintained at a normal temperature, and therefore it is customary to addto the tempering liquid contained within the receptacle therefor.Heretofore it has been necessary to stop the churning operation and insome instances to remove parts of the dasher in order that additionaltemperingliquid may beintroduced. Such stopping of the operation of thedasher has been found to retard the formation of butter and also toresult in an inferior quality thereof tively fixed in the axis ofrotation of the dasher, whereby the tempering liquid may be introducedthrough said inlet-opening While the dasher is in operation and withoutrcmoving any of the parts thereof.

Projecting centrally from the lower head 2 is a pivot-pin 9, which isadapted to engage a suitable socket provided in the bottom of thechurn-body with which the present form of dasher may be employed.

It is preferable to form the heads, the tempering-receptacle, and thedasher-blades from tin or other suitable sheet metal, so as to provide alight and durable dasher, which may be readily cleansed, and therebyprovide a sanitary device. Thus it will be seen that the angular shapeof the body causes an agitation of the cream independently of thedasher-blades, and the combined action of the angular body and thedasher-blades produces an exceedingly-eifective agitation of the cream.Furthermore, it will be seen that the hollow dasher-stem permits thetempering liquid to be readily introduced into the angular body and thatit prevents such liquid from being accidentally discharged into theinterior of the body of the churn.

What I claim is- A device of the class described comprising a receptacletriangular in horizontal section and composed of side walls and upperand lower heads having radial arms extending ontward from the angles ofthe receptacle, the

upper head being provided with an opening
